*Abstract*:



We introduce a multivariate multidimensional mixed-effects regression model
in a finite mixture framework. We relax the usual unidimensionality
assumption on the random effects multivariate distribution. Thus, we
introduce a multidimensional multivariate discrete distribution for the
random terms, with a possibly different number of support points in each
univariate profile, allowing for a full association structure. Our approach
is motivated by the analysis of economic growth. Accordingly, we define an
extended version of the augmented Solow model. Indeed, we allow all model
parameters, and not only the mean, to vary according to a regression model.
Moreover, we argue that countries do not follow the same growth process,
and that a mixture-based approach can provide a natural framework for the
detection of similar growth patterns. Our empirical findings provide
evidence of heterogenous behaviors and suggest the need of a flexible
approach to properly reflect the heterogeneity in the data. We further test
the behavior of the proposed approach via a simulation study, considering
several factors such as the number of observed units, times and levels of
heterogeneity in the data.
